The invention relates to methods of and machines for spinning andaftertreating artificial silk.

In the method of spinning and aftertreating artificial silk according tothis invention freshly spun artificial silk is wound on winding carriersof a form similar to a hoop or felly after the carriers have been moved,by means of a common rotatable supporting structure, into a position foractuating and winding the same which is situated on the side of theartificial silk spinning machine adjacent to the spinning bath vat andin which the carriers are supported and actuated at their circumferenceand from which position the winding carriers on being wound withartificial silk are moved, by turning the supporting structure, to aposition of delivery situated on the rear side of the spinning machinefrom where the carriers are passed into aftertreatment means, thesupporting structure moving during this turning movement a fresh set ofempty hoop-shaped winding carriers having been previously insertedtherein into the position for actuating and winding the same.

This method offers the considerable advantage that the artificial silkneed not be touched with the hands from the moment of generation to thevery end of the aftertreatments to which it is subjected, as during allthe operations carried out in connection with the aftertreatments thematerial is permanently accommodated in one and the same machine.

In the accompanyingdrawings the method according to the invention isillustratively exemplifled, in which a constructional form of the ma-'chine for carrying the method into eifect is shown by way of exampleonly, this machine also forming part of the invention. In the drawings-Fig. 1 shows a sectional elevation of the machine;

Fig. 2 is an end view of the rotatable supporting structure showing thedrive of the latter to be arranged at this end;

Fig. 3 shows a fragmentary side elevation partly in an axial sectionalong the line AB in Fig. 1;

Fig. 4 shows an elevation of a modification of the rotatable supportingstructure;

Fig. 5 shows an axial section of the drive, and

Figs. 6 and '7 each represent a sectional elevatlon of two differentmodifications of a detail, viz. the arrangement of two aftertreatmentvessels instead of one only.

Referring particularly to the Figs. 1 and 2 of the drawings, the numeralI refers to the frame of the machine at one side of which the spinningbath vat 2 and the water gutter 3 are arranged, whereas at the otherside of the machine frame a tub 4 containing an aftertreatment liquidsuch as wash water or a desulphurizing solution is positioned. 'On theupperside of the machine frame 5 l mounting supports 5 are secured inwhich a hollow shaft 6 has its bearings. Between each two adjacentmounting supports 5, on the hollow shaft 6 two bearer members i and Sfor one and thesame supporting structure are arranged (Fig. 10 3), oneof which being in the form of a hollow body providing at the same time amounting disk 9 for the hollow shaft 6 in the adjacent support 5. Theother bearer member 8 is rigidly secured to the central shaft 6 at theside of the other mount- 15 ing support 5.

The bearer members i, 8 are each provided with two diametricallyoppositely disposed arms ii! and H (Fig. 1) each for receiving therespective end of two shafts l2 and 53 on which rollers l4 and 20' 15respectively are mounted. The individual bearer members i, 8 resemble aspider with the arms I0 and i l extending in the cross direction to theother arms. In addition to being interconnected by the shafts I2 and I3at the shorter arms, the two bearer members i and 8 of one and the samesupporting structure are joined at their longer arms by two shafts H3and i9 (Figs. 1 and 3) and besides by two further shafts 20 and 2!, thelatter shafts extending through one of the adjacent supportingstructures or else even through several such structures as arranged onthe same common hollow shaft 6.

In the mounting support 5 shown to the left in Fig. 3 the twothrough-shafts 20 and 2| are passed through the mounting disk 9 of thebearer member I of the next following supporting structure. Theindividual hollow bearer member l accommodates two chain drives 23 and26 for operatively interconnecting on the one hand the shafts l8 and 2tand on the other hand the shafts l9 and 28. This construction has theadvantage of providing an adequate and safe supporting, i. e. bearingengagement for the through-shafts as many times in the length of themachine as required.

The two shafts 20 and 2!, which are positioned nearest to the centralshaft 6, are provided on their ends shown to the right in Fig. 3 whichproject out of a gear wheel 25 secured on the hollow shaft 6 (see alsoFig. 2) with driving pinions 26 and 21 respectively. A gear wheel 29secured to a shaft 28 (Fig. 3) cooperates with the gear wheel 25 forcommon actuation of the supporting structures carried by the centralshaft 6. On a shaft 30 (Fig. 3) a gear wheel 3! is fixed which mesheswith the pinion 721 on the shaft 2 l, as shown, for rotating the shaft 2l. By periodically turning the supporting structure, i. e. the row ofsuch structures, through angles of 180 the pinions 26 and 21 arealternately moved into engagement with the stationary driving wheel 3i,so that each time one of the shafts 2t and 2! and together with it thatone of the two shafts l8 and H? which is coupled to the respective shaft20 or 2| are actu ated by means of the correlated chain drive 23 or 24.

Consequent thereon, rollers 32 and 33 respectively are turned dependingon which pair of operatively interconnected shafts 20, I8 or 2|, H! areactuated, the rollers 32 and 33 serving for supporting and drivingWinding carriers 34 of a form similar to a hoop or felly, as will beseen in the Figs. 1 to 3. It will be readily'understood, that acomparatively large number of winding carriers 34 can be arranged sideby side in the length of the individual supporting structure, thewinding carriers being merely supported at their raised circumferentialedges.

In the position of the supporting structure shown in Fig. l the windingcarrier supported by the rollers 33 of the pair of shafts 2! and I9occupies a position designated by I for actuating and winding thecarrier. To this end, the shaft 2! is coupled to the drive shaft 33 byinterengagement of the wheels 2i and 3! (Fig. 3), the winding carrierthus being circumferentially actuated by the rollers 33 turning togetherwith the respective shafts 2! and I9. In this manner the artificial silkthread 36 emanating from the nozzle 35 is wound on the winding carrier34 turning in the direction of the respective arrow shown in Fig. l bymeans of a guide 3?.

On this winding carrier 3 3, that is, the entity of winding carriersoccupying the driving and winding position I respectively being woundwith artificial silk, the supporting structure, i. e. the entire row ofsupporting structures as provided are turned through an angle of 180 bythe main shaft 28 (Fig. 3) in the direction of the arrow designated byII. By this rotational displacement the wound winding carriers 34 aremoved from said position I into the position of delivery as indicated byIII in Fig. 1 from whence they are passed on towards the aftertreatmenttub 4, as will be hereinafter more explicitly explained.

On the termination of the said rotational displacement of the supportingstructure, a fresh set of empty winding carriers, which had beenpreviously placed on the supporting structure at the delivery positionIII occupies the driving and Winding position I. This fresh set ofwinding carriers then rests on the rollers 32 of the two shafts I8 and2B which on the termination of said rotational displacement of thesupporting structure are moved into operative engagement with the driveshaft 36, the two longer arms of the bearer members I, 8 and the twoshorter arms thereof having mutually changed their positions. At thesame time the shafts l9 and M are disengaged from the drive shaft 30during the said rotational displacement of the supporting structure, sothat the driving movement of the winding carriers supplied with materialis stopped and the still oncoming artificial silk is passed over to thewinding carriers having been moved into driving and.

winding position due to the rotational displacement of the supportingstructure, these carriers being thus wound with material.

The supporting structures present in the machine are inclosed by acasing 38 (Fig. l) partly of arcuate cross section and provided with aclosure lid 39 situated in the vicinity of the position III fordelivering the filled and inserting empty winding carriers.

In the constructional example of the machine shown in the drawings thecasing serves for securing the fellies against dropping off thesupporting structure. It is, however, possible to construct thesupporting structures without departing from the spirit of theinvention, in such manner, that the fellies stick to the supportingstructure by themselves, without the aid of the casing, until theyarrive at the lowermost position at the rear for dropping off by beingreleased from the supporting structure. For this purpose it is onlynecessary to prolong the arms l0 and II and to render these armsslightly yieldable, in order to provide for the carriers to be retainedin position during the rotational displacement without cooperating withthe casing but to be free to drop oiI in the respective position at therear.

As the follies are brought to the position for leaving the supportingstructure, the casing must be opened to leave the way free for them tobe removed. To this end the closure lid 39 is connected to the lowerpart 41 of the casing through the intermediary of a shaft #8 so as to beadapted to be rocked into open position by means of a crank drive 42,43. The casing joins with its lower part 4! with one of the longitudinalwalls of the spinning bath vat 2 and is provided above the otherlongitudinal wall of this vat 2 with a window panel 44 and at theceiling with a flue 55 for educting the gases which accumulate in thespinning and winding space inclosed by the casing as Well as in the,aftertreatment tub 4 in the di rection of the respective arrow. Theflue communicates with the said uncased space by conduits 46 arranged ona common level.

During the rotational displacement of the supporting structure the woundwinding carriers 34 being moved out of the actuating and windingposition I are held in position on the supporting rollers and therollers M or I 5 respectively by the arcuate portion of the casing,whereby the windingv carriers are prevented from rolling out of thesupporting structure as they are swung over to the delivery position. Onopening the lid 39 by means of the crank drive 62, 43 the wound fe-lliesoccupying the position of delivery III disengage from the supportingstructures by gravitatively rolling on the open lid 39 which had beenpreviously rocked to enter the tub 4 with the cover 5'! of the latterbeing removed. In this way the winding carriers are permitted to roll orslide into the tub 4 inside of which they come to stand on hearingstrips 48.

In Fig. 1 two intermediary positions of the winding carriers on theirway from the position of delivery III to the tub 4 containing theaftertreatment liquid for the artificial silk are indicated by chaindotted lines. After in this fashion a set of fellies wound withmaterials has been removed from the supporting structures into the tub1, a fresh set of empty hoop-shaped winding carriers is put in theirplaces on the supportingstructure. This is accomplished by at firstplacing the fellies on the lid 39 having been rocked back into aconvenient position and then closing the lid, thereby the fellies areinserted into the supporting structure, that is, between two arms of thespider, as will be readily understood.

During the next following rotational displacement of the supportingstructure, which takes place after a period of time necessary forwinding a set of'winding carriers, the winding carriers which had beenpreviously inserted in empty condition are carried along by thesupporting structure in such a manner, that the carriers roll on thelower arcuate portion of the casing until they are raised to a levelpermitting the carriers to rest against the rollers 32 or 33 on theshafts I8 and 28 or 9 and 2| respectively, in which condition ofsupporting the winding carriers arrive at the driving and windingposition.

It is of eminent importance that the rotatable supporting structuresinclusive of the fellies, which parts together are of a considerableweight and the former being eccentrically loaded, are moved out ofposition free of shocks and entered into position of rest free of shocksagain. Furthermore it is essential that the supporting structures areevery time adjusted to and retained in the same respective positions ofrest accurately.

In the Figs, 4 and 5 a device well adapted for thispurpose is shown. Onthe central hollow shaft 6 a disk is fastened the circumference of whichis provided with two oppositely disposed recesses 55. One of theserecesses cooperates with an actuating pawl, 52 which is arrangedlaterally on a chain wheel 53 rotatably mounted on the disk 50.Alternatively, two actuating pawls 52 may be connected with the chainwheel 53, one each for cooperation with either of i the two recesses 59of the disk 59. Round the chain wheel 53 a chain 54 is passed the oneend of which is attached to a crank while from the other end acounterweight 56 is suspended. The parts 50 to 54 form oonjointly alocking device operating in one direction of driving only.

During turning the crank 55 in the direction indicated by the arrow inFig. 4 the chain wheel 53 is actuated by the chain 54, thus rotating thedisk 59 and consequently also the central shaft 5 in unison therewith bymeans of the actuating pawl 52. In this manner the bearer members of thesupporting structures and thus the structures themselves are alsoactuated, the former being, as aforementioned, firmly connected to theshaft 6. i

In Fig, 5 only one bearer member I is shown which is, however, devoid ofhollow arms as the chain drives 23 and 24 between the pairs of shaftsi8, 20 and l9, 2! respectively are here arranged at the side of thebearer member I.

The rotation of the chain wheel 53 and thus that of the supportingstructures is positively effected at least during half a revolution ofthe crank 55 from A to B, whereupon the driving motor is stopped or acoupling is disconnected respectively which serves for connecting themotor with the shaft IE1. Consequently, the chain wheel 53 is idlyturned back by action of the counterweight 56 into its initial positionA. This position represents at the same time the starting position forthe next following positive operation of the shaft Iii.

During this operation the pawl 52 slides on the disk 50 in order toenter into engagement with the opposite recess 5| after eachdisplacement of the supporting structure by an angle of 180 aspring-pressed locking lever 51 cooperates with one or the other of twonotches 58 in the disk 50 by which means the supporting structure issecured in the respective position of rest. Both of the diametricallyopposed notches 58 are situated in a raised rim on the disk 50.

The described driving arrangement serves the purpose to impart to thesupporting structures of a large size a gradually accelerated startingmovement and a gradually decelerated stopping movement during therotational displacements of the same in order to provide for thestructures to depart from and to arrive at the respective positions ofrest free of shocks. In carrying out these displacements it is importantthat the shaft Hi carrying the crank 55 moves at certain intervals in apositive manner through at least half a revolution and is adapted topass the dead center position B and that, by action of a counterweight,such as a spring or the like, the crank 55 is returned into the initialposition A in a dependable manner.

In the modified arrangement of the aftertreatment means shown in Fig. 6,in addition to the tub 4 a further tub 4 is provided for cases where theaftertreatment of the artificial silk wound on the winding carriers iseffected in two successive working phases in two separate tubs. Thefirst working phase takes place in the upper tub- 4 into whichthe'fellies 34 wound with the artificial silk are fed from the deliveryposition III by opening the lid 39 provided on the casing 38 and afurther pivotal lid 58. In this construction the lid 39 is rockedupwards by means of the crank drive 42, 43, as evident from thedrawings, whereas the lid 60, which is mounted on a shaft 6! andconnected with a crank drive 63, 64 by means of a tension member, isrocked downwards by means of the latter crank drive. The tub 4 istiltably arranged by means of trunnions 59.

After the artificial silk has been subjected to an aftertreatment in thetub 4 while still in position on the winding carriers, which had beencon- 'veyed into this tub from the position of delivery III, the tub 4is rocked into the chain dotted position thus permitting the windingcarriers to roll out of the tub 4 and to drop into the tub 4' which hadpreviously been uncovered and in which the artificial silk is to besubjected to a second aftertreatment on the winding carriers. On thewinding barriers being removed from the position of delivery III intothe tub 4, a fresh set of empty winding carriers can be inserted in thesupporting structures at the said position.

In Fig. 7 a further modification of the aftertreating arrangement isshown wherein the second tub 4' is positioned at the side of the tub 4approximately at the level of the latter. This arrangement provides forcompletely aftertr-eating the artificial silk as supplied to theindividual tubs in position on the winding carriers 34 in the respectivetub. In this arrangement the wound winding carriers 34 can be passedfrom the position of delivery III into the tub 4, the cover 41 of whichhad been previously removed by opening the lids 39-and provided on thecasing 38 or by passing the winding carriers across the cover 41 of thetub 4 on opening the lid 60 into the tub 4' after the cover 49 of thesame had been removed. The possibility of passing the wound windingcarriers selectively from the position of delivery III into one or theother of the two tubs is of particular importance in all cases where theaftertreatment of the artificial silk requires more time than thespinning and winding operations.

Naturally more than two tubs may be provided for the aftertreatment.
